Intel is set to upgrade its entry-level desktop Pentium and Celeron product lines in the first quarter of 2013 with the launch of Ivy Bridge-based 22nm Pentium G2130, G2020 and G2020T and Celeron G1620, G1610 and G1610T processors.

Its existing Sandy Bridge-based 32nm Pentium G870, G645 and G645T as well as Celeron G555, G550 and G550T will be phased out of the market starting the end of 2012, according to sources from the upstream supply chain.
